Slf'II-IICIEICATIO.N formingA part of Letters Patet No. 343,138', dated June 1, 1886.

. ,l Application tiled October 1-2, 1885.

,Be it known that I, TIMOTHY MCHUGH, of

Boston, in the county of Suffolk-and State of Massachusetts, have invented c ertain new and useful Improvements in Couplings for Water- Closet Bowls, of which the following is a specivlication. f 1' `Ihis'invention has for itsobject to enable a metalpipe to be quickly and firmly connected ro to the tubular neck of a water-closet bowl,

l and at the same'timeprvide againstall danger of. breaking the parts; and it consists in the combination, with said'neck, having at its outerend a shoulder, of a rubber ring formed r 5 Yto cover the shoulder and the end of the neck,

Va pipe formed to bear against the end of the ring that covers 4-the end of the neck, and a f coupling-nu'tformed to engage said pipe, and having aflange which bears either' against the end of the rubber ring ,that covers the shoul-` der on the neck and the periphery of the neck, between said end andshoulder, or against a loose ring interposed between the Bange and ring, all of which I will now proceed to describe.` l l' p Of the accompanying drawings, forming a, part of this specication,Figure 1 represents f a lsectional view of a part of a'water-closet `bowl and the .pipe connected thereto by my improved devices.' Fig. 2 represents a similar view of a modification. Figs. 3 and 4 repre` .The same letters of reference indicate the same partsin all thefgures.

3 5 In the drawings, c represents a water-closet bowl, and b` l the tubular neck near the upper;l

edge of the bowl, through which the water enters to flush the-bowl, l'a ,water-pipe, c, being coupled to said neck'. i ,f

Incarrying-out my invention I provide the outer end of the neck with a shoulder, d, which maybe the inner Aside of a flange projecting outwardly from the neck, as shown in' Fig. l, or one edge of agroove formed in the neck, as

shownin Fig. f2.

' represents a ring of yielding rubber, formed to cover both the outer lend ofthe neck and the shoulder d.

f represents a"cou ling-nut, whichis formed 5o to engage with the t readed end of the pipe c,

Serial No. `179,670. (No modem audhas av flange, f', projecting inwardly behind the inner edgeof the rubberring.

I prefer to interpose between the flange f and the rubber ring a loose ring, g, of metal, so that the rotation of thenut is not attended with so much friction as it would be if the. flange bore directly on the rubber ring, yand danger of breaking the neck b by torsional strain is avoided.

In the construction shown in Fig. 1 the internal diameter of the ilange f is greater than that o f` the iiange on theneck b, to; enable the nut'jC to be passed over said flange, and the ring gis divided into two parts, as'shown inv Fig. 3, or it may be otherwise 4suitably con' structed to enable it to be placed on the neck b, the internalgdiameter of the ring g being such that it lits the body of the neck somewhat. closely.A Y ,It will be observed that `the rubber ring, engaged, as shown,\with the neck so that it canf not be displaced by pressure Yexertedlengthwise of the neck, constitutes a collar which is ,engagedwith the neck by` its own elasticity,

and supports the coupling-nut f, and also a. packing which is compressedbetween the endx of the neck band the pipe c, and insures a,tight joint by merely turning .up the 'coupling-nut with' the hand.` Thusthe construction of rubber ring and its relationship tothe other parts of the invention are such as to make it serve not only Iasta packing-ring or washer, asis common in couplings of this character, but also as a cushion to the several parts, whereby p all danger of breaking the neck of the bowl by torsional strain in the act of coupling the parts is avoided. 4 I am aware that it is old andecommon to'\ employ rubber in the forni of rings or Washers in the construction of couplings, and I do not 9ol lClainrthiS, broadly, confining my invention to the construction andarrangement -ofthe parts 1 stated. v The parts are few and simple, and therefore inexpensive and not liable to get out of order.A

Iclainil l., The combination of the neck b, having a shoulder, d, a rubber packing-ring formed to coverboth the endlof the neck and the shoul'- ,100

pointed outinf' the claims, for the purposes l der d and the periphery of the'neck between said end and shoulder, a pipe, externallyscrew-threaded end formed to bear against the upper ring, formed to engag the threaded portion of the k pipe c, and having a flange between which and )twn said endand shoulder, the threaded pipe c, the coupling-nut f, having a'flange, f', and

`the loose metal ring interposed between the flange'fand the ring e, as set forth.4

3. The combination of theneck b, having a ange at its outer end, the rear side of which c, having an and a coupling-nut forms a shoulder, d, the rubber ring e,- formed to cover the end of the neck and its Bange, the zo threaded pipe c, the coupling-nut f, the flange f', formed to pass over the flange of the neck, and vthe divided loose .ring interposed between the fiangef and ring e, and having a smaller internal diameter than'the flange, so as to have z 5 an extended bearing on the ring e, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, this 10th day of October, 1885.

TIMOTHY MCHUG.
